We have multiple Active Directories in our company, such as :
finance-dc1.company.com
finance-dc2.company.com
sale-dc1.company.com
sale-dc2.company.com
development-dc1.company.com
development-dc2.company.com
...
Our development team want to authenticate (bind) and search users against one AD and not multiple ADs, so is there any solution to have a replica of all ADs into one AD (e.g: proxy-dc.company.com)?
